Given Input Data is 945, 393, 127

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 945 is 3 x 3 x 3 x 5 x 7

Prime Factorization of 393 is 3 x 131

Prime Factorization of 127 is 127

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(945, 393) = 123795

GCD(945, 393) = ( 945 x 393 ) / 123795

GCD(945, 393) = 371385 / 123795

GCD(945, 393) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 127

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(3, 127) = 381

GCD(3, 127) = ( 3 x 127 ) / 381

GCD(3, 127) = 381 / 381

GCD(3, 127) = 1

GCD of 945, 393, 127 is 1
